About the Center for Fetal Diagnosis and Treatment at CHOP

The Center for Fetal Diagnosis and Treatment at The Children’s Hospital of Philadelphia is an internationally recognized leader in fetal surgery and fetal care. One of the only programs of its kind in the world, it offers a comprehensive breadth of services, including fetal therapy, to support patients from prenatal evaluation through delivery, postnatal care, and long-term follow-up.

Established in 1995, the Center has welcomed more than 12,000 expectant parents and received referrals from all 50 states and more than 50 countries. Its multidisciplinary team brings decades of experience to the care and treatment of the fetus and the expectant mother.

The Center has performed more than 900 fetal surgeries, including complex open procedures for birth defects such as spina bifida; less invasive fetoscopic or ultrasound-guided surgeries for conditions such as twin-twin transfusion syndrome; and specialized coordinated delivery approaches for babies that require surgical intervention while still on maternal-placental life support (EXIT delivery).
